The owner of a ship has in all cases an insurable interest in it, even when it has been chartered by one who agrees to pay him its value in case of loss.
Freightage, in marine insurance, signifies all the benefit derived by the owner, either from the chartering of the ship or its employment for the carriage of his own goods or those of others.
The owner of a ship has an insurable interest in expected freightage which he would have certainly earned but for the intervention of a peril insured against.
The interest mentioned in the last section exists, in the case of a charter party, when the ship has broken ground on the chartered voyage. If a price is to be paid for the carriage of goods it exists when they are actually on board, or there is some contract for putting them on board, and both ship and goods are ready for the specified voyage.
